Detailed Description

template<typename C1, typename C2>
struct tt::sync_clock< C1, C2 >

A clock which converts one clock to another clock. The new clock is similar to C1 (slow clock), except that leap seconds from C1 are filtered out. Leap seconds are filtered out because calibration to the slow clock does not happen often enough to react in-time to a leap second.

This clock is most often used to convert a cpu_counter_clock to a hires_tai_clock.

Parameters

C1	A clock with known epoch and known frequency.
C2	A monotonic clock which may have an unknown epoch and/or unknown frequency.
